To cut the excessive self-weight and redundancy of an aerial work platform's outrigger mechanism, this paper presents a lightweight workflow - multibody dynamics load extraction, finite element strength analysis, SIMP topology optimization, manufacturability-oriented reconstruction, closed-loop verification - on the integrated Siemens Simcenter Inspire platform, targeting Outrigger 1. Using extreme multibody dynamics loads as boundary conditions, topology optimization is run at a 25% design-space volume fraction under an extrusion constraint, and three reconstruction schemes are compared. After optimization the maximum von Mises stress is 195.7 MPa, the displacement 2.548 mm, and the minimum safety factor 1.1; strength meets requirements, the mass drops from 1353.921 kg to 111.911 kg (a 91.7% reduction, i.e., the remaining mass is only 8.3% of the original), and the trajectory matches the prototype without interference.References
